We're dividing 166537 by 72 
We want to divide 166537 by 72.

Going ahead to step 1:
72 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 72

On to step 2:
If we divide 16 by 72, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 72

Step 3:
If we divide 166 by 72, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 144 from 166 to get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 72

On to step 4:
When dividing 225 by 72, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 216 from 225 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 72

Moving on to step 5:
93 divided by 72 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 231.0
If we take 72 away from 93, we end up with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 72

On to step 6:
When dividing 217 by 72, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 2313.0
Deduct 216 from 217 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 72, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2313.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
72 goes into 100 1 times with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 2313.01
The remainder is 28 after subtracting 72 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
280 divided by 72 is 3 with a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 2313.013
Deduct 216 from 280 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
When dividing 640 by 72, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 2313.0138
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
When dividing 640 by 72, we get 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 2313.01388
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 2313.01388 with a remaining 6.4e-05.
